It describes the main waste sources, including urban growth, tourism, mining, small and remote communities, and natural disasters, and explains how steep terrain, remoteness, and limited infrastructure increase management costs and risks. The document outlines typical waste streams and governance arrangements, noting frequent gaps in collection, treatment, and disposal, particularly in developing contexts. It highlights the downstream impacts of poorly managed waste on water, ecosystems, and human health. The report also documents existing practices, institutional roles, and broad categories of solutions and capacity needs presented across diverse mountain settings.
